Google Spaces is a discontinued mobile app for group discussions and messaging developed by Google. The app was intended to compete with Slack as a content sharing platform where users can create a "space", invite their friends for discussion, and share videos, images, text, and other media. Google services such as the web browser Chrome, search engine Google Search, and video sharing platform YouTube were built into the app to allow users to source content from them. Google Spaces launched on May 16, 2016, available on Windows, Mac, Android, and iOS operating systems. The app was discontinued on April 17, 2017. The Spaces brand name was revived for an unrelated feature in Google Chat, formerly named Rooms.
